Sodium Silicate

Sodium silicate, usually known as “water glass” or “liquid glass”, is well-known due to wide commercial and industrial application. It is mostly composed of oxygen-silicon polymer backbone lodging water in molecular matrix pores.
Uses -

• In Metal repair - Sodium silicate is used, along with magnesium silicate, in muffler repair and fitting paste. Muffler is a device for reducing the amount of noise emitted by the exhaust of an internal combustion engine.
• In Automotive repair leaks -  Sodium silicate can be used to seal leaks at the head gasket. A head gasket is a gasket that sits between the engine block and cylinder head in an internal combustion engine.
• Car engine disablement -  Sodium silicate solution is used to inexpensively, quickly, and permanently disable automobile engines.
• As Adhesive -  Sodium silicate was used to seal combustible nitrated paper together to form a conical paper cartridge to hold the black powder, as well as to cement the lead ball or conical bullet into the open end of the paper cartridge.
• Aquaculture -  Aquaculture Sodium silicate gel is also used as a substrate algal growth in aquaculture hatcheries.
• Refractory use -  Water glass is a useful binder of solids, such as vermiculite, the natural mineral that expands with the application of heat and perlite, volcanic glass that has a relatively high water content.
• Concrete treatment -  Concrete treated with a sodium silicate solution helps to significantly reduce porosity in most products such as concrete.
